Detailed Description
The invention will be further described with reference to the following drawings and specific examples, which are not intended to limit the invention thereto.
The invention provides a contour forming blade for processing stainless steel products, as shown in figures 1 to 5, the contour forming blade is arranged on a handle 1, a plurality of cutter grooves are concentrically arrayed at the end part of the handle 1, a square blade body 2 is arranged in each cutter groove, first cutting edges 3 are respectively arranged on four sides of the blade body 2, second cutting edges 4 are respectively arranged on two sides of each first cutting edge 3, each first cutting edge 3 is connected with two adjacent second cutting edges 4 in a concave shape, a forming surface allowance removing process can be completed by replacing two hard alloy cutters with one contour forming blade, certain production cost is saved, in addition, the first cutting edge 3 and the adjacent second cutting edges 4 form an obtuse angle, and the value range of the included angle is an obtuse angle
That is, A indicated in FIGS. 2 and 3 has a value range of [1 DEG, 2 DEG ]]In the machining process of the blade with the right-angle profile, the actually machined point is the outermost point, and the rest straight line part does not cut the workpiece but generates sliding friction with the workpieceThe invention solves the sliding friction in the processing process of the forming surface, improves the problem that the cutter point is easy to break in the processing process of the contour forming blade, prolongs the service life of the blade, reduces the production cost, and ensures that the included angle between two second cutting edges 4 at the same vertex angle is 90 degrees.
The first cutting edge 3 and the adjacent second cutting edge 4 are connected through a fillet with the radius of 0.2mm, the fillet is firstly contacted with a workpiece and is positioned at a processing boundary, the abrasion is serious, and the quality of a processed product is seriously influenced, so that a negative rake angle is formed between the R0.2 arc and a boundary abrasion serious area, namely a rake face of the first cutting edge 3 and the horizontal direction, the value range of the negative rake angle is [ -10 DEG, -15 DEG ], namely the value range of B in figure 4 is [ -10 DEG, -15 DEG ], a protective edge band is formed, the problem of boundary abrasion in the processing process of the blade body 2 is solved, and the size and appearance consistency of the product is ensured.
The front surface of the blade body 2 is also provided with a cutting groove 5 for chip removal along the edge, the cutting groove 5 is smoothly connected with the front blade surface of the second cutting edge 4, the radius value range of the cutting groove 5 is [0.8mm,1.2mm ], the phenomenon that the cutting groove greatly influences the overall strength of the blade body 2 is avoided, and the overall structural rigidity of the blade body 2 is ensured.
When the conventional contour forming blade is put into use on a production line, an operator is difficult to realize ordered transposition and inspection in the transposition process, so that part of a group of used cutters is used too frequently and reaches the service life, and therefore, the group of blades cannot realize stable processing, and the cutters often need to be replaced in advance.
The above description is of the preferred embodiment of the invention; it is to be understood that the invention is not limited to the particular embodiments described above, in that devices and structures not described in detail are understood to be implemented in a manner common in the art; any person skilled in the art can make many possible variations and modifications, or modify equivalent embodiments, without departing from the technical solution of the invention, without affecting the essence of the invention; therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
